A 37-year-old Chicago man has been charged with the gruesome murder of his 2-year-old son.

Rolando Ortiz faces one felony count of first-degree murder. He allegedly slashed at the neck of his son, Mateo Garcia Aguayo, nearly severing his head on Wednesday afternoon at the family’s apartment on the Southwest Side.

Authorities said Ortiz attacked the child because the toddler had prevented him from getting to sleep. When the father realized what he had done, police say, he tried to slit his own wrists before fleeing.

“Mateo wasn’t old enough to make a bad decision,” Chicago Police Supt. Eddie Johnson said at a news conference. “Mateo wasn’t old enough to take the wrong path in life. He was just an innocent kid whose trust and safety was betrayed by the one man that he should never have to question.”

The father allegedly told family members about killing the boy, whose body was found in a garbage bag.

Illinois State Police intercepted Ortiz in Kankakee County, where he was taken into custody. The suspect allegedly confessed to police and said he had been heading to Mexico.
